NWT Sleep Number King Sheet Set ("Winter Soft" Plush Microfiber, Navy Blue)

These sheets from Sleep Number are the softest and warmest you'll ever encounter! They're like plush, fluffy, lightweight blanket material. Sleep Number calls it microfiber. (It is 100% polyester.) Like all Sleep Number sheets, these are high quality and certified STANDARD 100 by OEKO-TEX, meaning safe from harmful substances. This set is NWT, never opened/used. It includes 1 flat sheet, 1 fitted sheet, and 2 pillowcases. All pieces are made of the same material. The color is called "Midnight," which is basically dark blue. The size is King -- regular King, not California King, or Split King. This means these sheets will fit non-Sleep Number King-size beds, as well. The fitted sheet measures 80" x 76" x 13"; the flat sheet 110" x 100"; and the pillowcases 40" x 21" (inches). The yarns in these sheets go through a shearing and brushing process to give them a soft, plush feel. As a result, this fabric will produce some lint. After the first several washings, the amount of lint will diminish. Machine wash cold separately, gentle cycle. Tumble dry low. These sheets normally retail for $140. They were purchased directly from SleepNumber.com. They'll ship in a breathable, double-zipper storage bag that has a handle. Because these sheets are so plush, the shipping box will be relatively large. The storage bag measures 18 inches x 14 x 7 -- and the shipping box will be larger. I'll have to pay Poshmark/USPS a shipping overage fee to send this. The price reflects that fee.
